I am getting Error = 9006 when downloading some Podcasts

10-11  Source: Network gathering  Views:1 

I am getting Error = 9006 when downloading a podcast, Derb Radio on TakiMag, but not other podcasts.  It started occurring recently, about 3 of the last 4. This occurs on both a Windows and Apple machine.  iTunes is updated.  It does not occur with other podcasts.  Then end result is that the podcast does not download.
I also get a "rebuffering stream" interruption during playback on the computer.
